- `isDefault` – whether the model is recommended for most users
- `nextCursor` – pass into the next request to continue paging (optional)
The server also emits `model/presets/updated` notifications after initialization and after auth state changes (login/logout). The payload is:
- `models` – the full list of available models, with the same shape as `model/list` items.
## Event stream
While a conversation runs, the server sends notifications:
- `codex/event` with the serialized Codex event payload. The shape matches `core/src/protocol.rs`’s `Event` and `EventMsg` types. Some notifications include a `_meta.requestId` to correlate with the originating request.
- Auth notifications via method names `loginChatGptComplete` and `authStatusChange`.
- Model catalog notifications via method name `model/presets/updated`.
Clients should render events and, when present, surface approval requests (see next section).
